METHOD AND MEANS roit-nara nme'rnmarrc mes.

' Application files To allwhomit ma concern: v v Be it known t at '1Leon Gi HannnN- BnooK, a citizen of thellnite'd States, residing atLyndon, in the county of Whatcom. and State of Washington, have inventedcer tain new and useful Improvements in Metheds and Meansf or RepairingPneumatic Tires, of which the following is a specifica tion, referencebeing had to the accompany? in' dravirihgs.

his invention relates to an improved method and means for patchingpneumatic tires, and has for its primary object to provide a simple andeffective means and method of applying the same to a pneumatic tirewhich will efi'ectually close a puncture therein and preclude allpossibility of the escape of air or the entrance of water. ,Consideredin its more specific aspect, the present invention contemplates theprovision of a tire patch consisting of a section conforming intransverse contour to the tire to be repaired, which may be cut from anold tire, said patch section having beads upon its opposite ends,. thebeads of the tire upon which the rim flanges are adapted to be clenchedbeing cut away to receive the beads of the tire patch, whereby saidpatch is tightl drawn and clamped upon the periph- 30 cry 0 the tirewhen the same is applied to the rim and secured thereon.

With the above and other objects in view, myinvention consists in thenovel features of construction, combination, and arrangement of parts tobe hereinafter more fully' described, claimed, and illustrated in theac.- companying drawing, in which, i

' Figure 1 is an elevation of a portion of an automobile tire, showingthe same punctured and prepared for the application-of my improved shoeor patch thereto; Rig. 2 is a similar view showing the repair patchapplied Fig. 3 is a transverse section taken on the line 3-3 of Fig. 2;and Fig. 4 is a detail perspective view of the patch or shoe.-

Referring in detail to the drawing, 5 des ignates the ordinary pneumatictire such as is commonly employed u on automobiles and other motorvehicles; The longitudinal edges of the tire are provided withcontinuous outwardly projecting beads 6. In Fig. 1, it will benote'd'that the tire has been punctured, as at 7. The two longitudinalbeaded of the tire are cut away and removed 55 from the tire body, asindicatedat 8,such

cut away portions of the beads extending beyond the opposite ends of thepuncture? r'oved patch or tire shoe, generally" I by the numeral 9, isof substan tially the same diameter as the tire to be repaired, andconforms in cross-sectional con-. tour therewith. This patch or shoewhich may be constructed of rubber fabric or other suitable material, isof sufiicient length to entirely cover the puncture or hole? andprovided upon its opposite ends with out-f wardly projecting beads 10corresponding in cross-sectional area and shape to the beads 6 of thetire. These beads 10 are adapted to x be received in the gaps or spaces8 from, which, sections of the heads 6 on the tire are; cut. Z

After applying the tire patch-for shoeto the tire in the manner abovestated, the til-oi 5 turned flanges of the rim. plates or sectionsindicated at 11 engaged o'ver the beaiis 'iil and 10. f In the clampingor clenchin 8c: tion of the rim sections u onzthebea s of the tire andthe patch ,lsai patch is drawn fio inwardly until the beads 10 thereonare in alinement with the heads 6 of the tire, so that the periphery ofsaidtire is compressed, as'indicated at 12. Thus, a very,

tight and secure clamping action of the 3 shoe or patch upon the tire,is obtained,and the uncture or hole therein efiectually closed The tireatch being of water proof material, absolute y prevents the entrance ofwater or other -for ei :matter' to the in? alsopbviates all lia From{the foregoing description, taken in connection with the accompanyingdrawg', ing, the construction of my improved tire'f patch or shoe andthe method of using oiap lying the same 'willbelfully and clearly lunerstood; The shoesior patch sections-1 may becut from an oIdtire; orthey may be separately manufactured andjsold. 196 The device,whilejextreme'l' simple in its construction, is, nevertheless; iig'hlyserviceable'and efiicient in practicaluse, and pro'- vides a veryconvenient emergency tire patch T which may be readily applied by theindividual user --without necessitating the eni.-' ployment ofnaiskilledworkman.

I have above*ref,erred 'to the preferred form and construction of thedevice; but it will be understood that the same is susceptil ble ofconsiderable modification therein and I I, therefore, reserve theprivilege of adopt ing all 'such obvious modifications as may b'efairlyembodied within the spirit and scope of the invention as claimed.

Having thus fully described my invention, what I desire to claim andsecure by Letters Patent is 1 The herein described method of repairinga' punctured tire which consists in cutting away sections of thelongitudinal tire beads, then applying to said tire over thepuncture, apatch section conformingin cross-sectional contour and in diameter tothe tire and having beads upon its ends to be received in the spacesprovided by cutting away the beads of the tire, and then applying thetire with the patch to the wheel rim and clenching the rim upon saidbeads whereby the patch is drawn inwardly into clamping engagement uponthe wheel tire.

2. A patch for repairing punctured pneumatic tires consisting of aflexible patch member conforming in cross-sectional contour to, thetireand having beads upon its opposite ends, the longitudinal beads ofthe tire being cut away, such cut away portions extending beyond theopposite ends of the puncture, and the beads upon the patch member beingengaged by the clenching flanges of the wheel rim'and drawn into thespaces thus provided in the tire beads, and

said patch member clamped upon the wheel tire and caused to exert acompressing accut away, such cut away portions extending upon oppositesides of the puncture in the tire, said patch member being adapted forengagement upon the tire over the puncture therein and thebe ads thereonengaged by the clenching flanges of the wheel rim and drawn intothespaces in the tire beads whereby said patch is clamped upon theperiphcry of the tire and caused to exert-a compressing action upon thesame.

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses.
